How can I detect negative Hex Values in C#? -


i working on driver temperature sensor. values coming in hex form , stored like:

string temphex = "08c5"; //-> 22,45°c

the problem is, sensor can notice negative values , have no idea how can detect 2's complement in c#.

maybe can me. thank you!

static public double temp(string hex) {     return convert.toint16(hex,16)*0.01; }

values 0000 7fff positive, 8000 ffff negative. luckily, convert.toint16() you, how numbers stored internally on modern computers. have multiple 0.01 celsius.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
